This paper sets out a framework to evaluate the welfare impacts of residential energy efficiency programs in the presence of imperfect information, behavioral biases, and externalities, and then estimates key parameters using a 100,000-household field experiment. Several results run counter to conventional wisdom: we find no evidence of informational or behavioral failures thought to reduce program participation; there are large unobserved benefits and costs that traditional evaluations miss; and realized energy savings are only 58 percent of predictions.
Q41: Energy: Demand and Supply
Scientists believe significant climate change is unavoidable without a drastic reduction in the emissions of greenhouse gases from the combustion of fossil fuels. However, few countries have implemented comprehensive policies that price this externality or devote serious resources to developing low carbon energy sources.
